During the PCB design process, we will encounter various grounds, such as digital ground, analog ground, chassis ground, etc. This is also a very troublesome problem for our engineers in the design. If the ground is not handled well, there will be various interferences. I hope that through this live broadcast course, everyone will be able to handle the ground clearly, so that the ground in everyone's PCB design will become calm and will not cause any disturbing waves.

I wrote an AD conversion program for MSP430F149. I burned it into the microcontroller and found that it always displays a number (not zero, 1.77V) when there is no analog input voltage. I checked the

The driver I wrote before can be used normally. Today, I need to use it. I took out the program and found that the program can't be used. It always stops in the busy query loop. I don't know what's go
